Hello! I am Shemhaza, the Guardian (Sentinel). Suddenly, how many passwords do you remember? Banks, SNS, shopping sites… you've probably noticed you use many passwords. But are those passwords really secure? If that "key" were to be broken, your valuable information might be stolen by a thief. Today, I'm going to tell you the secret to password management that will protect you and your family from unseen dangers.
Are Your Passwords Really Safe? Unseen Dangers Are Approaching
- ▸① "Reusing" passwords is like giving a thief a master key. If you use the same password for multiple services, just one service leaking information can lead to all your other accounts being easily hijacked. This is as dangerous as having one house key stolen and then having your car and safe opened.
- ▸② "Simple passwords" are easily broken. Birthdays, phone numbers, pet names, or short passwords like "123456" can be quickly discovered by cybercriminals using automated "dictionary attacks" or "brute-force attacks." It's like using a key that anyone can open.
- ▸③ Leaked passwords are exploited in "credential stuffing attacks." Unfortunately, without us knowing, password information can sometimes leak from a service we use. Cybercriminals compile this leaked information into lists and launch "credential stuffing attacks" to attempt unauthorized logins to many people's accounts. If you reuse passwords, you become an easy target for this attack.

- ✓When registering for a new service, make sure you create a "new password."
- ✓Avoid using "easily guessable passwords" such as birthdays, phone numbers, or common words.
- ✓Ensure you set a "long and complex password" (10 characters or more is a good guideline) by mixing uppercase and lowercase letters, numbers, and symbols.
- ✓Consider using a "password manager" to securely manage many passwords.
- ✓For services that allow "two-factor authentication" (identity verification methods other than passwords), always make sure it's enabled.
Where to Seek Help When in Trouble
If you suspect your account has been hijacked or your password has been leaked, immediately change your password and contact the service you are using. If unauthorized use of credit card information is confirmed, immediately contact your card company and proceed with stopping its use.
